Re: GSoC 2010: ZooKeeper Failure Detector Module

2010-05-11 Thread Abmar Barros
Thank you Adam!

I had a first look at you code and your implementation will
be certainly useful.

Cheers!

 Hi Abmar, cool project!

 I wrote an implementation of the Phi Accrual Detector which I would be
 happy to donate. It has the nice property that its parameters are
 based on expectation odds rather than something more arbitrary like #
 retries.

 You can steal it at http://github.com/arosien/failure. It works well
 but let me know if you have any suggestions.

  Hello all,
 
  As Henry Robinson first introduced me, my name is Abmar Barros and I am
 one
  of the GSoC accepted students for ZooKeeper.
  In the next 4 months, I will be being mentored by Flavio Junqueira in
 order
  to improve ZooKeeper's failure detector module. In this project I will
  abstract the failure detection code to a separate module, in order to
 make
  the code cleaner and to ease the implementation of new methods. Also, I
 will
  implement several failure detectors and I will compare their
 appropriateness
  for ZooKeeper.
 
  I have created a page (
  http://wiki.apache.org/hadoop/ZooKeeper/GSoCFailureDetector) for this
  project in the ZooKeeper wiki and also there is a related JIRA issue (
  https://issues.apache.org/jira/browse/ZOOKEEPER-702).
 
  Suggestions and specific requirements are always welcome :)
 
  Best regards
